dont worry yourself much bro, that's another easy part as along as you have the money you will get an apartment. Dont rent anything now until you see the place and many of us will be here when you get here to show you the place and get you situated. its better to stay by the old campus since there is more to do and you have more access to all the stores. as you get closer the chicago office will give you a list and you can start making contact, so 2 things to remember come down 3 to 4 days early, and check out hotel rocheline in bonaire online and make a reservation to stay there for a few days and we will take care of you.
on a side note i dont like the idea of doing pre-med here though for many reasons that have been discussed on these forums.
